Post-blast explosive residue : a review of formation and dispersion theories and experimental research

The presence of undetonated explosive residues following high order detonations is not uncommon, however the mechanism of their formation, or survival, is unknown. The existence of these residues impacts on various scenarios, for example their detection at a bomb scene allows for the identification of the explosive charge used, whilst their persistence during industrial explosions can affect the safety and environmental remediation efforts at these sites. This review article outlines the theoretical constructs regarding the formation of explosive residues during detonation and their subsequent dispersal and deposition in the surrounding media. This includes the chemical and physical aspects of detonation and how they could allow for undetonated particles to remain. The experimental and computational research conducted to date is discussed and compared to the theory in order to provide a holistic review of the phenomeno

The Concept of Business Judgment

Categorising something as a business judgment can provide directors with a powerful shield from accountability. It has been said that the courts in England and Wales defer to directors’ business judgments and directors’ decisions are protected from review in other jurisdictions by a business judgment rule. Yet what a business judgment is has never been addressed, and so precisely what is being protected, and why, is unclear. This paper analyses case law in England and Wales and key Australian and US cases to answer this question. It argues that the courts use the term judgment in two senses: an ability, and a decision sense, and that business judgment in both senses can be linked to Knight's concept of entrepreneurial judgment, and directors’ wealth creation function. Conversely, decisions that are linked to directors’ corporate governance function and are less easy to categorise as entrepreneurial are less likely to be viewed as business judgments
